Abstract:
This heat exchanger is equipped with: a first heat exchange unit having a first intake/discharge unit which has one intake/discharge port and through which a coolant flows, and also having a plurality of first heat transfer pipes, each of which has one end thereof connected to the first intake/discharge unit; a header pipe which is connected to the other ends of the plurality of first heat transfer pipes; and a second heat exchange unit having a second intake/discharge unit which has two or more intake/discharge ports and through which a coolant flows, and also having a plurality of second heat transfer pipes, each of which has one end thereof connected to the header pipe and the other end thereof connected to the second intake/discharge unit. The coolant flows from the first heat exchange unit side toward the second heat exchange unit side during heating and flows from the second heat exchange unit side toward the first heat exchange unit side during cooling. In addition, the second heat exchange unit has a larger heat exchange surface area, which is the surface area across which heat exchange between the coolant and air occurs, than does the first heat exchange unit.
